Abstract

Investigation of the 95% EtOH extract of stems of Dendrobium findlayanumafforded four new seco-dendrobines, findlayines A–D (1–4); two known dendrobines, dendrobine (5) and 2-hydroxydendrobine (6); and four new phenolic compounds, dendrofindlaphenols A–C (7, 9, and 10) and 6″-de-O-methyldendrofindlaphenol A (8). Compounds 1and 2are the first seco-dendrobines possessing a seven-membered lactam moiety, with 3and 4derived from the oxidative cleavage of the C-2–C-3 bond of dendrobine. The structures were established using spectroscopic methods and by comparison with literature data. The absolute configurations of 1–4were confirmed via single-crystal X-ray diffraction data. Cytotoxic activity assays against HL-60, SMMC-7721, A-549, MCF-7, and SW480 human cancer cell lines revealed IC50values ranging from 2.3 to 5.3 μM for compound 7, from 19.4 to 34.4 μM for 8, and from 49.4 to 96.8 μg/mL for the EtOAc extract. An assay of the inhibition of NO production with RAW 264.7 cells indicated that 8had an IC50value of 21.4 μM, and the EtOAc extract, 10.5 μg/mL. The EtOAc extract possessed DPPH radical scavenging activity of 69.93% at 100 μg/mL.

Abstract

Objective: To analyze the expression and clinical characteristics of CD68 in bone marrow and peripheral blood of patients with acute myeloid leukemia (AML)., Methods: The expression of CD68 in bone marrow blast cells was detected by four-color flow cytometry in 50 newly diagnosed AML patients and 23 controls. The expression of CD68 in peripheral blood of 85 newly diagnosed AML patients, 29 remission AML patients and 24 controls was detected by ELISA. The correlation between the expression rate of non-M3 AML bone marrow CD68, peripheral blood CD68 concentration and white blood cell count and other clinical data was compared respectively., Results: The median CD68 expression rate in myeloid leukemia cells of non-M3 AML patients was 19.7%, significantly higher than control (0.2%) (P<0.001). The median concentration of non-M3 CD68 in peripheral blood was 67.97 pg/ml, significantly higher than in control (29.94 pg/ml)（P<0.01）. There was no statistically significant difference in the plasma CD68 concentration of the peripheral blood between the newly diagnosed (45.72 pg/ml) and the remission stage (55.12 pg/ml) of non-M3 AML patients by paired analysis (P>0.05). The results showed that the higher the expression rate of CD68 in bone marrow, the higher the count of white blood cells in peripheral blood, and the lower the count of hemoglobin and platelet in peripheral blood. The higher the plasma concentration of CD68 in peripheral blood, the higher the white blood cell count and the lower the complete remission rate., Conclusion: The expression of CD68 both in bone marrow and peripheral blood of patients with non-M3 AML is higher than that of control group. Patients with high expression of CD68 show a low rate of complete remission, suggesting that the expression level of CD68 is correlated with treatment response.
